To all vwhom lit may concern:

Be it known that I, EDWARD E. CLUSSEN,

making pulp receptacles. As a part of/the inventionl is a method. The receptacle "may i.

be vemployed for a varletyof different purposes.

In the drawings accompanying and formingpart of the present specification l have shown one of the several convenient forms of embodiment of the invention, and this l will setforth rather fully in the following description, primarily to enable those skilled inthe art'to practice the invention. As' anr incident thereto the method as to one desirable form will be disclosed. As will be `inferred, l am in no sense restricted .to this particular showing; l may depart I therefrom in several respects for both as to the machine or apparatus and the method there are, I believe, certain broad features .involved. The resultant article made by the machine or apparatus or the method for that matter, may be employed for different purposes. l might note vat this juncture, however, that the machine shown is particularly organized for making what is known as a pulp bottle. bly primarily intended to contain milk, it is adapted just as well to receive other liquids, semi-liquids or solids for that matter. Referring to said drawings:,. Figure l is a side elevation of the machine with parte in section. y

Like characters refer to like parts throughl out the several views, which are on different, scales. Y

ll have several motives'in view. One of my aims is to force pulp of suitable character into a mold of properv kind. This pulp 5 .may obviously be directed into the mold jin any. desirable way, vair pressure being generally utilized for the purpose. I prefer thatthe air pressure be napplied in such manner as to blow away the water in thepulp while a part of the bottle or other article is being pressed or otherwise acted upon. As a matter of fact I prefer a roller or its equivalent to Secure these results, the action of the roller or analogous means being such as to press the bottle within the same to leave a smooth interior. This roller also functions to loosen the bottle from the screenkthroughout the entire extent thereofL when occasion arises therefor. also desire to employ what li term a cage to jlay on the layers of pulp. l/Vhile the foregoing is a concise description of somel of the primary features in the invention, I am as will be inferred in no sense restricted thereto. The machine is designedin units, merely one of which is shown and will-be hereinafter described. More of these units may be added if desired.

The different parts of the machine will be supported by a suitable framework. That shown comprises in its make-'up the basexor bed 2 provided with several pendent legs as 3 to rest on a floor or other suitable foundation, and if necessary to be bolted or otherpair of columnsoruprights as 4: rising from the back of the base or bed near the ends thereof, and tied together at suitable intervals by crossbars as 5.`

-Within the base or bed is mounted a' pan as 6,-the bottom of which consists of two portions which as shownconverge'just for- K ward of the transverse centerlineof-the bedY or base Around the marginal portion of this pan vis a groove or gutter as 7 in which` the water falling onto the bottom of the pan can iiow to be disposed 'fof as mayibe'desirejd, this water being merely leakage that may occur during the production of a pulp article. I might observe at this point that when I use the term pulp I do so in a generic sense, not only ,tu include paper stock` but anything of 'an equivalent nature.

.The machine has several parts which are actuated by some convenientv source of power and the mea-'ns shown for this purpose will now be set forth concisely at least at this point. The same involves a main or power shaft as 8 supported by one-ofthe columns or uprights 4, the one on theright in Fig. 3. This shaft 8 carries at its'outer end 'the' pulley or band wheel 9 fastened thereto in some suitable-way and belted up to Na convenient mat-ing pulley or band wheel which I have not deemed it necessary to show.

The mold construction maybe of any suit- C; able nature, and in this connection reference ter as' I will hereinafter explain, ,functioning l vready Y Aclosed there is vacylinder presented, having .53ga body or'walled-part, a bottom practically .60.,

EI 'ffreason that will hereinafter appear.

should best behad to Figs. 1, 5 and' `6. The lower. cross bar 5 is shown as provided with a forwardly extending shelf or support 10 which constitutes a convenient.carrier for a mo-ld such as that denoted in a general wa'y b y 1l. .This mold 11 I might note is of 'sectional form, comprising in thepresent case four practically similar segments 12. When these segments mate or abut, the mold 11 is closed as shown by Figs. 5 and 6; a cylindrical .structure is thus presented. The segments 1.2 are as shown provided at theirup. per and lower ends with ears or projections 13 extending outwardly therefrom and practically ytangentially thereto, these ears terminating in hubs or sleeves `14 rigid as represented, .with the rodsl or barsJ 15 which y are also practically cylindrical in shape and which are hollow at least for' a portionof" their lengths, the hollows or bores bein denoted by 16 and eJxtendf ing from vt e lower ends of the-rods or bars to a short distancev above the shelf o1', support 10, for a reason that will hereinaften appear; There arein the present .case four ofthese rods or 15, and they are lat the corners of-a` rectangle. They are .also dis-i posed between the parallel rods 17, thelatinthe opening and closing of the mold 11.

Each segr'nentil2 of themold carries two of the ears l13 situated near the upper and lower ends thereof. The moldl as willbe understood', com risesa bottom as 18 and atop as 19. As lwi l also be clear, said `bottom and. top` each consist of four segments rigid for instance. by being' made. inte al,K4 with the respective segments 1,2 to which I have al-y referred, so that when the mold is imperforate, and a top partly open for a The ttom1518 hasfacro iton the upper side th rechi-the `radially disposed strips '20. These extend up from the bottom 18 I and are' spaced, how.

ever, from'the interior of th'e body of the mold at their ends for a reason thatl I will hereinafter explain.

vIn addition to the mold there is what I have'already referred to as a cage, which performs a function in the production of the plastic article to be produced, and-such a cage as that denoted in a general way bv 21 meets my conditions. This cage like the mold lcomprises flo-ur practically similar segments 22. Themold I might observe has in the present case merely an opening and a closing movement, at which time the hubs 14 swing with the rods, bars or shafts 15. The cage 21 as I will hereinafter' explain partakes of this swinging movement, but in addition to this swinging movement it has also an endwise movement or one in a direction corresponding with the axes of the mold, and the cage, and the reason for this relative axial or endwise movement will also be hereinafter explained. The segments 22 are spaced from the respective segmentsg12, and these spaces between the two parts function as ways or duct-s. The segments 12 have at their lateral vedges the inwardly-projecting flanges 23 whicli 'extend Vthe complete length or depth of said segments and which are provided on their' inner faces, (their outer faces abutting when the mold is closed) with grooves or channels 24 throughout their entire extent, which slidingly receive the nall -extending keys 28 on said rods or sha s. In vview of this circumstance. it becomes clear that the hubs 27 'canslide on said rods or shafts 15. When, however, the rods -or shafts 15 are rocked, the sections of the cage vas well asthose of the mold will be either opened or closed, depending upon the direction in which the rodsor shafts 15 are rocked. The lower arms 13of the mold sections 12 are provided in turn with outwardly7 extendin arms 130 having'studs 131 whlc enter ho es 132 in the'bars 17. At the rightof the machine (Figs. 2 and 3) the bars 17 carry rollers 133 engaging cams 134 on the shafts 63. On the `lower sides of said bars 17 are projections 135 between which and the stationary brackets 10, springs are placed which close the section according to the timing of the cams 134.

The arrow 29 in Fig. 5 indicates the direction of retracting movement of the cage 21,

in4 its. extremeiretracted position at which time its upper end'abuts againstthe top 19 said. cage in fact fin said, view being shown iso of the mold. Advancing movement of the cage will of course, be opposite to the arrow v29. The mold 11 has interiorly there-4v of the flanges 30, these flanges being as i shown at right angles to the'strips 20 and be- I have already referred to the fact that there ing horizontal, although this may not always be necessary. These flanges are spaced apart for a reason that I will hereinafter set forth,

and they are rigid at their outer ends withv the sections or segments 12 of the mold and at their inner ends support what I term the is closed its shapeis practically that of theoutside of the bottle tol be formed. The screen obviously comprises a body and a bottom and each of itsy segments naturally involves a wall or body portion and a bottom portion, and when the mold is closed in the mannerI have already noted, the wall or body portion and the bottom portion of the screen mate to present a b'ottle-shapeds'creen. The sections of the screen are Aconnected rigidly to the spaced flanges or partitions 30 in any convenient way, and the sections or segments 22 of the cage move between the ends of these flanges or partitions 30. It

therefore, follows that on the opening of-v the mold 11 and the consequent opening of the cage 21, the screen 31 is likewise epened, rbeing fastened as I have already stated to the segments or sections 12 of the mold. I

is a roller which presses the article being producedsmooth on the inside andas anadditional function this roller. also loosens the bottle or as it might be considered blank from the-screen'31. The segments of the.

said rods 15 project into the pipes 141 for a reason that will be hereinafter stated..

. .50 Surmounting the mold 11. is what I term a cupy 32. preferably of rubber or some equivalent elastic or flexible material. This cup isinverted and its top 33 also of flexible material acts as a diaphragm as I will-later explain, in cooperation for instance with a roller andits adjuncts. This elastic., or flex-v ible cup 32 fitsjwithin the flange or bead 34 rising from the top 19, the flange orbodv being obviously. of sectional formL and its sections corresponding practically to those of the parts of the said top. This cup has an inlet as 35 in the form cf a tube= integral with the appropriate section ofthe body of the cup, this tube beingintended for the pas- 7 sage of pulp and air in desired order. The

inlet or tube 35 is connected with thesup` ply pipe 36 at practically the'lowe-r end thereof in a water and\airtight manner. This supplyy pipe hasv a rigid connection of some suitable kind with the framework of the machine on the forward upper portion thereof and its upper end is connected with a suitable source ofpulp supplyv which yI have not deemed it necessary to illustrate. In said pipe 36 near the lower end thereof isa casing for a valve as 37 of three-way type, this valve being operable to first admit sequently to admit air, the latter being utilized to blow out the surplus 'or unnecessary water in the pulp, so that when the article is taken from the mold it is semi-dry or in a practically finished condition. It may be at times necessary to subject the article to some subsequent drying; at any rate theexcess or unnecessary water is` removed from the-pulp in a positive manner, but I realize that this particular point in itself is not broadly new with me.

' I will assume 'that the cage 21 is in its eXtreme retracted position as shown best in Fig. 5 and that as aconsequence its upper edge is against the top 19 of the mold, all of the mold parts at this time being closed. The threeway valve 37 will then be opened, automatically in the present case, thus permitting the flow of pulp", from the pipe 36 to the supply tube 35 and the consequent direction of the pulp into the closed screen 31. The pulp `will pass from the cup 32 naturally downwardly and into the screen adhering to the inner surface and.y body of the screen. The water that passes through pulp to the mold and its adjuncts and subthe screen flows vbetween the partitions 30 to the chamber 140, the channels of the lower arms 13, bores 16 of the rods 15 and into the pipes A 141 out of the machine. It will of course, be understood that before the pulp can be directed into the screen 31, it will be necessary to advance (by moving downward in the present case) tlie cage 21, and I will later describe how this particular action is effected. Un the advance motion of the cage the pulp can be directed against the screen and the amount of 'pulp adhering to the screen will depend upon the duration of time that the cage is left in a. given position. I have mentioned the fact that the` lcage Ais in its extreme retracted position in `Fig. 5.

at the place in transverse linel with the upper end of the cage. It is assumed that the valve 37 has been opened' to permit pulp supply. With this assumption in'view I will further suppose that the cage is advanced.'y As the cage is thus advanced or moved downward, as shown pulp will be permitted to flow v its forward movement.

into the screen and will adhere to thatsurface .thereof interiorly., of the same which has been uncovered in effect by the cage on movement of the cage, it is obvious that l can grade the thickness of the body of the bottle being molded. It may be desired and probably will be to have the neck of the bottle considerably vthicker than the of the cage.. It will be understood thatv the( cage completes its advance when in its lowermost position or practically as illustrated in Fig. l. 1

As shown (Fig. the main shaft 8 has fastened, to it the pinion 38 (see also Fig. l) in mesh with the spur gear 39- fastened to the shaft 40 which extends between and is'supported by the columns or uprights 4. This shaft -40rhasv rigid therewith, the cam 4l cooperative with the stud or roller 42 (see also Fig. .2) on the'ro-d 43 forked at its lower end to embrace said shaft 40 and connected at its upper end by a pivotal joint, for instance with the 'crankarm 44 'of the valve 37 situated at the junction of the pipes 36 `and 45,.the pipey 45l being for the vsupply of air from a suitable source. Connected to the rod 43 and also to the adjacent column 0ruprigl1t4 is a retracting spring 46. It will be supposed that' the main y.shaft 8 is in motion and that the mold 11 and cooperating elements are closed. At the proper point in the rotation o-f the shaft 40 the cam 41. will engage the anti-friction `roller 42 to impart Lan upward movement to the rod 43, thus stretching thespring 46 and.. as a consequence, opening the valve -37 to first, cause pulp supply which` is di-4 rectedintoythe mold andat a subsequent -.point, the direction of air into the mold to supply ofpulp andair. so

secure the` removal of surplus water. After the stud' or anti-friction roller 42. has vbeen operated by thecam 41,'\the spring 46 will impart la 'downward movement to the rod 43 to thus shut the valve 37 and stop further At the present time it will beunderstood lthatv I am assuming that the mold and the various parts connected therewith are closed in the condition for -instance as yshown by both Figs. 5-and 6'. J ust about the time the Avalve 37 is opened ,secure first the supply By timing this 1 teens-i.

of pulp and then the necessary air to the mold, the cage 2l is advanced, and l will now set forth a means by which this par` ticular condition is brought about. On the base or bed 2 at opposite sides thereof (Fig. 3) are brackets 47 which carry at their upper ends the rock shafts 48. On the forward ends o-f these rock shafts areI rock and crank arms 49 connectedat their lower ends by bars 50, it being evident that there are two of such bars. These bars are provided on their inner sides with flanges or beads 51 (Fig. l) which enter comp-aratively freely, channels 52 in the several hubs 27. The shafts 48 have 4in addition to thev rock arms49 other rock arms 53. While each shaft 48'is `equipped with two of ,the rock arms 49, it only has, however, one of the rock arms '53. Thelower ends of the two crank arms 53 are connected by a rod 54 which extends between the runs of the belt 55 onto which the finished bottle is dropped when the mold and cooperating elements are opened, as l .will hereinafter set forth. This belt 55 passes around the drums .56 and 57, the inner drum 57y being rigid with the shaft 58, the framing having suitable bearings to support-said shaft. Theshaft -58 carries a pulley 59'connected by a belt as 60 with a. small pulley -61 on the main shaft 8 so that the belt br carrier 55 is continuously operative, at least as long as the machine' is in action.r One of the arms 53 or that on the right in Fig. 3 has jointedv to it the-lower end of the'rod 62 lhaving a guide connection of suitable kind with the shaft`63 (F igf3), uthe stud oranti-.friction roller 64 on said shaft 63 being cooperative with the cam '65 fastened to said shaft 63 driven by bevel-gearing denoted in a general way by 66 (Fig. 2) and actuated' from the shaft -8.` When the machine, therefore, is thrown into action to accomplish a sequence of` movements, the cage 22 through the described parts is gradually advanced, the cam 65 being so shaped as to effect first a slow advance of the cage and then the subsequent advance at alittle higher speed, in view of `which circumstance the ulp at and around Cage 21 practically. coincident with the upper surface of the bottomrl8, and when the latter lrelation .ensues the water in the pulp constituting the bottom of the bottle blank is deposited on the screen and the water that throughout its entire extent so as to impartv is blown through the screen passes between 'the strips 20 through the channels of the lower arms 13, bores 16 of the rods 15 'and into the pipes 141 out Jof the machine. llt will be understood that during the lowering of the cage 21l the supply of air or equivalent is on, because while air is decidedly the vpreferable agent, it is within the boundsy of possibility that something else might bev utilized. When air is the factor and it is as I state, the preferred one I prefer also that it be heated.

There is within the screen 31 suitable means suchas the roller denoted in a general way by 67 which with cooperating means presses the inner surface of the bottle shaft 69. The active or smoothing portion of this roller body 68 is practically the same in form as the inner shape of the bottle be- [which in turn is provided with an-elementE ing formed, the roller body rolling the inner surface of the body of the bottle while the spherical head of the screw 70 rolls the bottom of the blank or bottom. The roller 67 is in the present case given what mightbe considered as a'gyratory motion, and owing to this condition the inner surfaces of the body and bottom can be uniformly and accurately smoothed Vout throughout their entire area. The roller body 68 has a peripherally flanged head 71 cooperative with a practically similarly shaped base or foot 72 at the lower end of the sleeve 73 on the shaft 74,-th'is peripherally anged base on. foot 72 cooperating with the head 71 and the tw feceiving between them an anti-friction bearing denoted in a general way by 75. The base or foot 72 lits closely or in an air and watertight manner in a central Aopening in the top, diaphragm or gasket 33, The rods or vbars 15 to which I have already referred are surmounted by a bracket or shelf 76 such as that denoted in a general way by 77 havin spherical" ange or skirt 79 -of the sleeve 73;

this permitsL` the necessary gyratory movement of the roller 67 without affecting the proper action thereof. The shaft 74fis connectedby a linkage connection suchas that, denotedV in a general way by 80 with the shaft 81 supported bythe bearing 82 on a bracket y 83 extending from the uppercrossbar 5. The

shaft 81 as shown is provided at its'upper end with a pulley 84 connected as shown by a cross belt 85 extending over the idler 86 .the bottle .is finished, it bein .that at this particular point t e cage 21 is a spherical way 78 to receive the fastenedvon the shaft 186 journaled in the uprights 4. On the outside of the upright (Fig. 3) this shaft 186 carries fastened thereto the pulley 187 which is driven by the belt188 from the pulley 87 on the main shaft 8. 1t will, therefore, be clear that when said main shaft is in motion the roller is given the necessary gyratory motion so as to smooth down the interior of a bottle which is being formed. It should be noted that the y.brought about in the present case by the dropping of the bottle and further by bringing the roller to a practically perpendicular -or upright position Wholly free of the lateral parts of the body. While this particular action may be obtained in any desirable way, I will now set forth the means for accomplishing this action. Through the hollow shaft 81 floats the rod 181 which is connected at its lower end to the linkage 8O and at its upper end the spool 88 to which is jointed the lever 89 on the shaft 189 journaled between its ends in the framework of the machine. At the outside and to ythe left-hand side (F ig. 3) the shaft 189 has fastened `theretothe lever 190 to which is jointedthe re'd90 operable by the cam 91 whichhas a` sti'idf92to engage the lower end of said rod 90 at'the proper point, so that through the lintermediate described parts the roller 67 will be brought to an upright position at the time understood in its eXtreme lowest or retracted osition. It will also be undersood that at t e same time the mold 11 and screen 31v are opened,

so that the bottle now formed, can drop onto the belt 55, the upper run of which moves toward the right in Fig. 1 as indicated by the arrow therein.

The action of the machine is as follows:

It will be assumed that the mold 11, cage 2,1 and screen 31 are closed as shown 1n Figs. 1, 5 and, which lconditions have been brought about in the manner set forth. Pulp will first be admitted into the screen 31 on the advance of the cage 21 from its eXtreme backward position. Air will be directedv into ythe mold, so as to cause the pulp to be applied to the inner surface of the foraminous or reticulated screen 31.v

This action is continued until thebottle is` fully formed at which time the cage 21 will have been so retracted thatv its upper edge 4is brought Hush with the upper surface of 'the bottom 18.' As the pulp commences to fiow the rollery'? stands uprightbut just beyond this point the r'oller is given its com# pound movement so as to rotate Vand at the same time revolve it, the revolutions gradually increasing in extent until the roller is brought into contact with the inner surface ofthe blank, just aboutthe time the blank is shaped up into a bottle. This roller continues to'traverse the inner surface of the bottlev in the manner I have described until l it is smoothed out tohthefrequired degree.

away for subsequent treatment of -any kind should the same be necessary. .lust about .lathe time the vbottle or blank falls onto the Y belt o-r carrier 55 the roller`67 is brought to l its upright. position in readiness to subsequently repeat the operation.

` InA Fig. 7 I show a mold and certain co-. Aoperating 'parts which are practically the same as 'those already described, for which reason I will luse the same characters with l prime marks.J The only difference or in fact the only appreciable differeneebetween this and what I have already described is in the roller. This modified form of roller I will denote in a general way by 100. It comprises a' bodyf101. Thisroller body 101 is `provided near its upper end/withl a sleeve 102 to receive the Vband 103 by @which the rol-ler 100 will be rotated. This roller 100 ,has through it theiboreorgpassage 101i` extending almost to the lower or foot end ofv the roller. From this bore or passage lead the outlets 105. yInto the bore orl passage 104 are directed the pulp and air'in sequence, the J.pulp passing alongthe bore and at the outlets105 onto therscreenl. 'The roller'OO is turned by power. While the roller 67 is also turned it is rotated, hows ever, by its'fri'ctional engagementl with the pulp which is to form the bottle.

In Fig. 8 the parts which correspond with those in Figs. lu to 6 inclusiveiwh'ere they' appearl will bear like charactersJ with double prime marks. In rthis case therollerA is not cylindrical but is in the form rather of a ,spoon denoted a. general way by. 1105 fixed to the lower end of the tubular shaft l1 11. AThis shaft is'given a rocking motion but does not turn. The active or rounded portion of tlie spoon; however,v does smooth down the interior of the bottle and densities the stock thereof throughout the entire -in ner surface which conditions of course exist with the other forms of rollers.

It willv be clear that the means in the article. being produced of jwhatever nature lthe same may be, functions to.' smooth and ---press the stock,A and` at the same'time, al-

thoughthis function is performedv at a later period, eects the positive separation of the bottle from the mold mechanism. It will also be clearthat it is possible that I may,

within the spirit of the invention reverse some of the actions.v It will be understood that the rsupply of the stock may be acconplished in other ways than those specified and the removal of the excess stockand su'- perfiuous -water may also be otherwise ob-J tained. As a matter of fact the invention comprehends certain broad conditions, and as already explained I have set forth certain ways of carrying the invention into effect to which I am obviously 'not restricted.

-I desire to make it clear thatwhat I have considered and termed a moldwhich is theiterm by which it has been known to me, isalso known to others asia separablecasing. What IV have considered afscreen has also been known as a screen mold. It is well also to make it clear what -are the move- ""ments ofthe screen or screen mold of which that denotedy by 31 meetsv my conditions. This screen mold lis given an advancing 4movement opposite to -the arrow 29 in Fig. 5 from its upper or retracted position which it is shown as occupying insaid View.. I have` also eXplainedfit is advanced by a gradual downward movement. i f

What I claimv is :t 1. The combination of 'a separable casing,

a cage witliin and spaced from the casing,

a screen mold within and spaced from the and the-screen mold to cause the cage to relatively uncover the screen mo1d, and (means for directing pulp into the screen mold.

' 3. The combination of an approximately imperforate cage, a frarninousmold screen 125 within and spaced from the cage., a casing surrounding and spaced from theeage,thel

axes of the three parts being approximately` coincident, means 'for relatively moving the E cage and theI mold screen in the direction of said axes to cause the cage relatively to ex v tudinal axes to cause the cagerelatively to pose the mold screen, and means for direct.- ;ng pulp onto the mold screen When the cage and the moldV screen are thus relatively operated, and for also directing air through the pulp mass on the mold screen.

4. The combination of a `mold screen, means for applying pulp onto the moldI screen Within the same, a rotary roller for applying pressure to the pulp upon the mold screen, and means for freeing the exterior` pressure ofthe mold screen therefrom, to thus release the pulp article, and means for disengaging the pressure applying means and the pulp article when the mold screen is exteriorly freed. 5. The combination ,of a bottle-shaped mold screen, means for supplying pulp into the mold screen and direct-ing it against the inner surface of the Wall and bottom portion of the mold screen, a roller'to rotate against the pulp and occupying an inclined position to the longitudinal axis of the screen during the rolling operation, and means for bring ing said roller with its axis conforming approximately to that of the mold screen.
